How many Standard Ethernet Network Interface by server ?

Hi
Huh... I'd like to install a RAC configuration with 2 server but i've a doubt.
When i list all network interfaces i've:
Server1
en0 Standard Ethernet Network Interface
et0 IEEE 802.3 Ethernet Network Interface
lo0 Loopback Network Interface
Server2
en0 Standard Ethernet Network Interface
et0 IEEE 802.3 Ethernet Network Interface
lo0 Loopback Network Interface
Is it good or not ? (probably not and documentation says that en0 and en1 must be present in the configuration). OK.
I'm under AIX 5.3 and by Smit i've an option intituled "Add a Virtual IP Address Interface". Is it possible to create the second Interface as a Virtual IP adress here ?
Thanks in advance
Regards
Den

Den,
Basically, you would be needing two separate interface cards for each participating node. The first one to connect to the public network and second for the use an interconnect. Not sure, if et0 is really an network interface, if yes, you should be ok.
VIP is nothing but an un-assigned IP address (in the same subnet as your public IP address) which is expected to be inactive before you install the CRS. This should be listed in your /etc/hosts file and/or dns server (if used). Not sure if adding VIP through the SMIT makes it active, if yes, then you might not want to use SMIT to set up the VIP.
This may help you with more information - http://download.oracle.com/docs/cd/B19306_01/install.102/b14201/preaix.htm#sthref378

  • Can I find out how many clients are connected to a server process?

    Hi, I am hoping I can find out how many clients are connected to a server process. This could be either a programmatic lookout number, a number in a log file etc.
    By the way, does lookout have any application (not data) logs? I have noticed that occasionally lookout will crash and I cannot find any logs to determine why, what processes were running, who last accessed it etc.
    Thanks

  • How many databases can run in a server

    How many databases can run in a server, how can we find how many databases are running there – in OS level for UNIX

    You can have as many oracle instances as your system resources and kernel parameters allow you to.
    A quick search to know how many oracle instances are running, check the OS processes:
    ps -ef | grep smon
    This will list all smon manadatory instance processes, this way you'll know how many concurrently instances are running.

  • How many standard business roles are there in CRM

    Hi Experts,
    I had a question in one of my exam.. please answer it
    question:- How many standard business roles are there in CRM?
    options were:- 2,3,4,5
    I think the options does not have the right answer , upto my knowledge it is more than 5. please help me with the appropriate answer
    Thanks
    Rahul Mathur

    Hi,
    There are approximately 40 standard business roles available in the latest version ehp3.
    As the version changes the business roles increases. Initially  there are only 3 std business roles..
    1.sales pro 2. marketing pro 3. service pro and along with IC Agent.
    Each BR above is loaded with huge no of transactions even though our aim is to for ex: create sales order...we use sales pro but all the sales related operations(transactions) are being loaded in to the system so along with the version improvements/releases SAP have divided each of these std BR as much as they can and thus the no of operations or transactions per BR is decreasing with each release....
    Thanks & Regards,

  • How to get active network interface name?

    Hi All,
    Can any one tell me how to get the currently active network interface name (Local Area Connection/ Wireless Network Connection/ other) either by using java SDK or win32 API.
    Is there any function to get the active network interface name in java/win32?
    Is there any procedure for it to get from observing registry keys.
    I found NetworkInterface class in java but not yet succesful in getting the display name of active network interface.
    Can anyone help me with partial code?
    Please help me.

    Use getLocalHost() then retreive the list of NetworkInterfaces and cycle through them until you find the one that has that address.

  • How many PXI Ethernet Cards supported in LabVIEW RT?

    How many ethernet ports does LabVIEW RT support.  If I put in several cards (such as PXI-8231, PXI-8232, or PXIe-8234) into a PXI chassis, then would I be able to configure and use them all?

    Hello kmcdevitt,
    It should be fine to have as many ethernet cards as you need in the PXI chassis. There's a global limit depending on the number of interrupt lines available on the motherboard (or PXI chassis), but it's up to around 16, depending on the controller. You would set them up using the Advanced Ethernet Settings section in MAX, as explained in this LabVIEW Real-Time Module Help article. I posted the 2011 help but this works for a few versions back, what version of LabVIEW RT are you using? Hope this helps!

  • How many concurrent connections that an ACS server version 4.2 latest patch can handle?

    I have about 50 routers and layer-3 switches that autheticate via tacacs+.  The AAA server used to be on a Linux machine running open-source tacacs+ built by me.  I have a perl script that will log into all 50 devices at the same time to collect statistics.  This script is multi-threaded.  Everything is working fine so far.
    I recently out-sourced the AAA function to a 3rd party company, not by my choice.  The 3rd party uses Cisco ACS version 4.2 with the latest patch running on Windows 2003 Enterprise Server with 16GB RAM and quad processors with quad-cores, IBM x3650-M2 hardware. The connectivity between the 3rd party and my company is through a DS-3 connection.  Maximum bandwidth over this DS-3 connection is less than 10Mbps at most.
    I noticed that for the past 3 months I have multiple failures with this perl script due to authentication failure with the ACS server.  If I just run the script again a few routers/switches, there are no issues; however, whenever I started the script to log into 50 devices all at the same time, it will fail.  If I made the configuration on all routers/switches to point back to the old open-source tacacs+ server, the issue goes away.  The minute I switched back to the
    new ACS server, the issue came back.  If I modified the script to hit one device at a time, it works fine.  I think it is the ACS server can not handle a lot
    of AAA requests at the same time.
    Does anyone know how many concurrent connections that an ACS 4.2, with latest patches on Windows 2003 Enterprise Server with lot of memory and CPU power, can handle?  I can't seem to find this anywhere on Cisco website.
    Thanks in advance.

    No, Im not saying ACS cannot cope.
    Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
    Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
    If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
    If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

  • What licenses and how many should be taken for SQL Server 2012 Standard Edition

    Hi,
    Could you help me please with my problem: what licenses (per core or Server + CAL) should I take for SQL Server 2012 Standard Edition for the following environment:
    SQl Server will be installed on VM with 1 core.
    Physical processor is Intel Xeon CPU E7-4830, 2.13 GHz, 2131 Mhz.
    Few people will have an access to the VM but SQL server is used for a web-application for about 200 users from Active Directory.
    Great thanks in advance,

  • Can I do automatic page refresh? How many of them can the web server take?

    I'd like to ask this question in both short and (if you be so kind) in long form:
    Short: Can a portion of my APEX page be set to refresh automatically ones every few minute? Not the whole page, just a portion. Would I have to use frames for that? Can they be invisible?
    Long: I'd like to create a web interface, which would allow multiple users to track duration of some tasks. More importantly it has to allow other users to see each other's progress (which task somebody is on, how long he has been on it down to several minutes). I understand to server side of it. However, the client side presents a problem of information refresh. I want users to be able to sit without touching their mouses or keyboard and see changes for other users as they happen.
    What do I mean by "as they happen?" Ideally, I'd like to present changes in real time. My brief research of Push HTTP technology, pointed toward Comet or Flash. However, I don't know much about web development and as of now, cannot commit too much time to learning new technologies.
    The second best option, is to update information every couple of minutes. Two question arise here. First is the "short" question - please see above.
    Let's say the page sections can be refreshed automatically. Then I have a question about the load. If I potentially get thousands of simultaneous users, each sending a refresh request every 2-3 minutes, how bad would be the load on the web server and on the network throughput. The amount of data passed can be small, but I am very concerned about the load on web server and the traffic. (I am planning to do virtual hosting with a web hosting company). Somehow I am not concerned about the load on the database (maybe I should be). All calculations will be put in a stored procedure, at least I can optimize it.
    Any other suggestions on how to approach this client refresh issue?
    Thanks a lot.

    These answers are helpful but I still need more info. The first answer suggests putting html refresh tag. But that would refresh the whole page, wouldn't it? I just need to refresh one region. Can it be done with html tag?
    I reviewed the Javascript code in the example referenced in the second answer. It showed that I can refresh a region using Javascript. It looks very nice. However, I need to refresh with data pulled from the database. I am not familiar with AJAX (need to lear JavaScript first) and I know that JavaScript cannot query database on its own. So I am not sure that this example is relevant.
    What I need is: Only 1 region of the page needs to be refreshed every 5 minutes. The rest should "stay put." Everytime the refresh is performed the database will be queried for new data by means of stored db procedure. Do I need to jump through hoops to do that or is it fairly straightforward thing to do?
    Thank you for your time.

  • How to configure a Network Interface?

    Hey guys.
    I'm very new to Solaris OS. I've now installed Solaris Express Developer Edition on my Laptop. After the restart of the installation,I find out, that my network don't work. I try to configure it with the network-admin-tool, but i can't add something, because the button "add" is nowhere in the window.
    Is it possible, that Solaris don't detect the interface and how can I see it?
    Thanks and sorry for the bad english :).

    Look for *e[0-9] (as nge0, nge1, bge0, le0, etc.) in:
    # dmesg | less
    or:
    # less /var/adm/messages
    Exaple:
    Oct 13 15:54:45 hostname nge: [ID 223987 kern.info] NOTICE: nge0: link up 100Mbps Full-Duplex
    "Unplumbed" interfaces maight not show up in the kernel log as they are passive. To "plumb" all supported interfaces:
    # ifconfig -a plumb
    # ifconfig -a
    (MS' ipconfig mimics ifconfig :o)
    If it lists say 'nge0' and you don't have /etc/hostname.nge0 then:
    # cat /etc/hostname.nge0
    cat: /etc/hostname.nge0: No such file or directory
    # uname -n > /etc/hostname.nge0
    (or # echo nge0 > /etc/hostname.nge0)
    Add the address to /etc/hosts and the netmask to /etc/netmasks and the defaultgateway to /etc/defaultrouter
    Example:
    /etc/hosts:
    10.0.0.1 gw.fqdn gw
    10.0.0.2 hostname.fqdn hostname nge0
    /etc/netmasks:
    10.0.0.0 255.255.255.0
    /etc/defaulrouter:
    gw
    You can change things on the fly with the comands ifconfig and route, but these files must be edited for a persistent boot configuration.
    You can list the entire PCI-tree with:
    # prtpicl -v | less
    Example:
    :model Bridge device
    :compatible (a2000003daTBL)
    | pci10de,373.1462.7250.a2 |
    | pci10de,373.1462.7250 |
    | pci1462,7250 |
    | pci10de,373.a2 |
    | pci10de,373 |
    | pciclass,068000 |
    | pciclass,0680 |
    :driver-name nge
    To see if your interface has a driver look for the PCI to driver-mapping in /etc/driver_aliases. Also check http://www.sun.com/bigadmin/hcl/ and http://www.sun.com/bigadmin/hcl/hcts/install_check.html
    (put /sbin and /usr/sbin in PATH, i.e. PATH=$PATH:/sbin:/usr/sbin;export PATH)
    (use "more" if you don't have "less")

  • How many CALs do i need? Server 2012 - Exchange 2013 - RDP

    Hi,
    (I apologize for the grammar and spelling mistakes, but im confident in the fact that the text is understandable. If not, please let me know. I have used UK English for spelling.)
    I did some research and read the following:
    (unable to post links, my email needs to be 'verified')
    And some MS pages regarding the CALs for Windows 2008 R2 (don't ask why).
    This is basically what i want to do:
    OS:                        
    Windows 2012 R2, possibly 2x because of the RDS role.
    Roles Server1:  Active Directory and Exchange 2013
    Roles Server2: File server and RDS
    Users:                 
    20
    PC’s:                    
    Approx. 15. Not sure about the exact numbers, but i am sure that there are more users than client pc’s.
    Users RDP:        
    Starting with 10 but eventually every user will be using RDP, so it might be also 20. The 10 we start with will not have the ability of logging into a client PC but RDP only.
    MS Software:    Outlook 2010 or 2013, depends on the support by MS.
    We are going to start with an AD with a home folder, roaming profiles and an email account. If everything go’s whell, we plan to start letting users connect tot heir workspace via RDP.
    I came to the following conclusion and need your input on this:
    20 User CALs, As far as i know, I need 1 user cal for an AD account and a RDP cal for
    one RDP account. Without a User CAL, i cant issue a RDP user cal, is this correct?
    20 RDP User CALs, does this mean that all my users can log into a RDS session via any client, even their own private pc?
    No Device calls, redundant?
    20 Exchange CALs, I am not sure about this one, the second link i found only mentions acces via web and mobile. I would also like to know if the Exchange CAL is per user or email. If it’s per user, then wat do i do with an email that is meant for multiple
    users?
    2 Server CALs, This is just buying 2012R2 isnt it? Does this also allow me to use one physically and the other as a VM in the physical one? Just asking, im not really going to use a VM.
    Hope you guys can help me out on this one, i didn’t expect the CALs would bet his complicated.

    Hi,
    Under Per User licensing, you need a license for each unique human that will access the software.  Based on what you have written above, below is a general description of the licenses you need:
    20 Per User Windows Server CALs
    20 Per User RDS CALs
    20 Per User Exchange Standard CALs
    1 Exchange Server 2013 Standard license
    2 Windows Server 2012 R2 Standard licenses
    Notes: 
    Each Server 2012 R2 Standard license allows you to install it on a physical server (up to 2 CPU sockets) with the Hyper-V role installed, and install it in 2 VMs.  The key here from a licensing perspective is the installation on the physical server
    is only being used for Hyper-V--if you use it for some other purpose (like AD, SQL, etc.) then you are only permitted to run 2012 R2 on 1 VM without an additional license.  Running your servers as VMs is the common and recommended method now, unless
    you have a specific reason not to.
    I listed two 2012 R2 licenses above because from your description I get the idea that you will have 2 physical servers.
    It is preferred to split key roles/functions onto separate VMs if possible.  For example, it would be preferred to have Exchange on its own VM(s).  This is obviously subject to your specific situation, budget, etc.  In smaller environments
    some roles will be combined in order to save money.
    I did not include licenses for Office in the list above.
    Yes, Per User licensing means the user can access the software from any device, even their own private pc.
    I recommend you purchase licenses through a MS volume licensing program that fits your needs.  Adding Software Assurance (SA) to your licenses will allow you to get the new versions when they are released as well as give some additional licensing rights.
    As always, it is essential to read the Product Use Rights (PUR) document, licensing agreements, terms and conditions, etc., as applicable to your licenses.
    I recommend you also take a look at the Office365 plans that include Office/Exchange/etc.  There are Exchange-only plans as well.  Depending on your needs it may be preferred to have your users access Exchange in the cloud and run RDS on premises.

  • How to install graphical desktop interface on Oracle linux server 6.2

    Hi
    I have installed Oracle Linux server 6.2 how i install graphical desktop interface on server class installation

    If this is in the very early stage I suggest to re-install the OS.
    Look out for the window to select the set of software to install. Leave Basic Server selected, but choose the Customize now ratio button. Select the Desktops group on the left side of the window. Choose at least the X Window System, Fonts and Desktop packages. To get a similar Desktop like in previous Enterprise Linux releases, add also the General Purpose Desktop and Graphical Administration Tools packages
